Online Fax Service Overview

What is an Online Fax Service?

What is online fax

An Online Fax Service is a web-based faxing software that you pay a subscription fee to use. Instead of feeding printed documents into a fax machine, Online Fax Services work by uploading computer files (.doc, .pdf, .xls, and many others) into the software and faxing them electronically to either a fax number or email address. Faxes sent are encrypted and stored online in a password-protected account.
